so i have been using rhino a extensively for a few months now and one thing i haven’t found the answer two so far not from lack of searching either.
so i design pieces and assemblies in rhino. and sometimes pieces can interchange between different assemblies. but the assemblies dont always have the same world coordinate system.
so what i am trying to do is as a simple example in the source file i have a part oriented to a hole and so i would think if i set the cplane to be in the center of the hole. on my other assembly i have the same hole but is on a different world cplane so i set my cplane to the same hole. now back to the source drawing i export with origin my part and then go to my new assembly and import it. and its no where close to the hole.
im familiar with autocad. and autocad does this flawlessly i set my ucs to the hole in the source. wblock the part out go in to the second assembly set the ucs to the hole and insert and works just the way i desire.
rhino IMHO out does autocad in everything except this point and i think its not rhino i just dont know how to do it.
